E-Series Power Plant MKII

Welcome.
We are delighted that you have decided to purchase a  product. Your new integrated amplifier is a Hi-Fi unit of the highest quality, designed and developed with a single aim as top priority: to satisfy the requirements of the audiophile music lover.
This unit is the embodiment of innovative thinking and solid quality, exploiting the finest materials and components available, and all these factors contribute to a machine which will satisfy your most stringent demands and your most searching requirements for a period of many years.
Our production areas are supervised by highly qualified expert staff, and all final production units are checked comprehensively by a fully automated, computer-controlled system to ensure uniformly high quality. We guarantee that our products meet our own specifications to the full.
At all stages of production we avoid the use of substances which are environmentally unsound or potentially hazardous to health, such as chlorine- based cleaning agents and CFCs.
We also aim to avoid the use of plastics in general, and PVC in particular, in the design of our products. Instead we rely upon metals and other non- hazardous materials; metal components are ideal for recycling, and also provide effective electrical screening.
Our robust all-metal cases exclude any possibility of external sources of interference affecting the quality of reproduction. From the opposite point of view our products’ electro-magnetic radiation (electro-smog) is reduced to an absolute minimum by the outstandingly effective screening provided by the metal case. Thanks to ist modular concept the Power Plant integrated amplifier can be adopted to your individual requirements: Phono MM (Moving magnet) or MC (Moving Coil) pre-amplifier modules can be installed to upgrade one of the line level inputs to an audiophile phono input. If the Power Plant shall be operated without the CD Player or the Music Player of the  E-series, a remote control set is available to operate all functions of the Power Plant amp. High quality audio cables and loudspeaker cables specially developed for our amplifiers are also available in the  product range.
We would like to take this opportunity to thank you for the faith you have shown in our company by purchasing this product, and wish you many hours of enjoyment and sheer listening pleasure with your Power Plant. T+A elektroakustik
**** All the components we use meet the German and European safety norms and standards which are currently valid. The operation instructions, the connection guidance and the safety notes are for your own good – please read them carefully and observe them at all times.

Front panel controls

With the front panel buttons all functions of the Power Plant can be operated.
All information about the operating state of the Power Plant is displayed by the LED lamps above the buttons.
In the following sections the functions of the front panel controls and display LEDs are explained in detail.
ON
(On / Off switch)
Pressing the ON button briefly switches the device on. When the unit is switched on the green indicator above the button glows. The device switches off by a long button press.
Caution!
The mains button is not a mains isolation switch. Even when the LED is not glowing parts of the machine remain connected to the mains power supply (Standby mode). The stand-by current drain is stated in the chapter entitled ‘Specification’.
If the unit is not to be used for a long period we recommend that you isolate it from the mains by pulling out the mains plug at the wall socket.
If the machine is switched off using the mains switch the energy consumption is 0 Watt. When switched off in this way, the unit cannot be switched on again using the remote control handset. If you wish to switch the unit on, first move the mains switch to the ‘1’ position.
** The integrated amplifier can also be switched on using the source buttons. If the source device you wish to use is connected to the integrated amplifier via an E LINK cable, selecting that source switches on the amplifier automatically.
Volume and balance
(balance setting)
** The control enables you to vary the level between left and right channels, e.g. to cope with asymmetric speaker locations.
To avoid any adverse effect on the sound, the balance range is limited to +0,6 dB / -8,0 dB. It is never desirable to reduce the volume of one stereo channel to zero.

• The level of amplification is the same on both channels when the control is at the centre position.
• Rotating the control clockwise offsets the stereo centre to the right.
• Rotating the control anti-clockwise offsets the stereo centre to the left.

Volume control employing a high-quality, ultra low-tolerance quadruple ALPSpotentiometer.
Rotating the control clockwise increases the volume. Turning the control anticlockwise decreases the volume.

PHONES
(headphones socket)
** Socket for stereo headphones with an impedance of at least 50 Ω. When listening using a headphone the speaker outputs must be turned OFF using the `MUTE` button.  ** Continuous listening to very loud programme material via earphones or headphones can result in permanent hearing loss. You can prevent harm to
your own health by avoiding long periods of listening at high levels when using headphones or earphones.
Source selection Selecting the listening source
To select one of the signal sources as the listening source, push the corresponding button briefly. The LEDS above the source buttons indicate which input is currently selected for listening.
**** The audio signals of the selected source device are present at the RECORD OUT sockets and can be used for recording the programme with an audio recorder
connected to these outputs.

| DISC / Music Player
When the Music Player is selected as listening source the different subfunctions
of this device (Radio, CD, Streaming Client) can be selected by the appropriate
buttons on the front panel of the music player.

(monitor switch)| Pressing the monitor button enables you to monitor the quality of a tape or CD recording (tape monitor function). Pressing the Monitor button switches the monitor function on. When the monitor function is in operation the LED above this button will glow.
**The tape monitor function only works if the recorder connected to the amplifier supports this function.
If no recorder is connected, or if the recorder does not support the monitor function, the music signal will be muted when you select the monitor function. If this happens, simply switch the monitor function off again.
MUTE|

Button for switching ON and OFF the loudspaker output.
This button can be used to switch the loudspeakers OFF when listening with
headphones.
The LED above the button will glow when the loudspeaker output is switched
OFF.
****The speaker LED will blink for some seconds during the switch ON
delay after powering the device ON.
If the speaker LED is blinking constantly for a longer time this indicates that the
protection circuit of the Power Plant has turned OFF the speaker outputs to
prevent damages to the device or to your loudspeakers.
Causes for the tripping of the protection circuit can be overheat, short circuit at
the speaker output or overload of the amplifier. For further information please
see also chapter ‘Trouble Shooting’.

Tone control functions LOUDN| The integrated amplifier is equipped with a volume-dependent tone control
(LOUDNESS) circuit, which compensates for the frequency-dependent
sensitivity of the human ear at very low volume levels, due to the characteristics
of aural physiology.
Pressing the LOUDN button switches the loudness circuit on and off.
The red LED above the button glows when LOUDN is switched on.
FLAT| The FLAT function by-passes the tone control section of the integrated amplifier
and therefore disables the tone controls. The frequency response is then
absolutely linear.
The FLAT mode is switched on and off by pressing the FLAT button.
The red LED above the button glows when FLAT mode is switched on.
In FLAT mode the controls have no effect.
The LOUDNESS function is also available in FLAT mode.
Recessed controls| In normal use the knobs for tone and balance are recessed into the front panel.
If you press any of the knobs, it projects from the front panel and can then
easily be rotated. In the centre position the index marker points up, and you will
feel the detent engage.
When the setting is correct, push the knob back into the front panel, and it will
engage in its recessed position again.
(tone controls)| To compensate for adverse influences on reproduction quality caused by your
listening room, or imperfect loudspeaker positioning, the integrated amplifier is
fitted with an active, infinitely variable tone control system.
The tone controls are deliberately designed to affect only the low frequencies
below 300 Hz (BASS) and the high frequencies above 4000 Hz (TREBLE); this
avoids unwanted coloration in the critical mid-range sound.
• When the tone controls are at centre, the frequency response is linear.
• Rotating the controls clockwise increases the bass or treble.
• Rotating the controls anti-clockwise reduces the bass or treble.

Remote control handset

If a T+AMusic Player or CD Player is present in your system, the Power Plant can be controlled using the F100 / FM100 remote control of the player via the E LINK control interface.
If no Music Player oder CD-Player is present, an optional remote control set FBS100 can be obtained from your T+A dealer.

Installation Using the system for the first time Safety notes
This section describes all those matters which are of fundamental importance when setting up and first using the equipment. This information is not relevant in daily use, but you should nevertheless read and note it before using the equipment for the first time.
Back panel connections

A2 / TV| Universal line level pre-amp input for connecting any audio sources or TV sets.
---|---
A1 / PH| Universal pre-amplifier line input This input can be upgraded to form an input for an analogue turntable by fitting a Phono MM or Phono MC module (optional accessories). The T+A  phono modules can be precisely matched to your pick up system using the adjustment switches of these modules. For further information please
consult the operating manual of the phono module.
GND
Ground terminal| The ground lead from an analogue disc player is connected here in order to avoid hum.
A3 / TUNER| Universal line level pre-amp input for connecting any audio sources like tuners
DISC / MUSIC PLAYER| Input sockets for connecting a T+A  MUSIC PLAYER or a CD player.
RECORD| Input and output sockets for connecting devices which can record and play back (recorders).
PRE OUT| Pre-amplifier output for external power amplifiers or active speakers.
(loudspeaker terminals)| One pair of loudspeakers can be connected to the amplifier (SPEAKER R and SPEAKER L). The impedance of each speaker must not be lower than 4 Ω (DIN rating).
The output stages are designed to cope with a minimum load of 2 Ω, but continuous operation at  very high volume produces high currents in the
power output stages which can lead to overheating. This in turn trips the protective circuit which switches the amplifier off automatically.
Caution!
Make sure that the terminals are firmly screwed down, and that no short- circuits are possible as a result of projecting cable ends or errant wire strands.
Note: If the loudspeakers are to be used in countries outside the EU the red/black
stoppers can be removed from the loudspeaker terminals. The speakers can then be connected using banana plugs.
The stoppers are simply a push-fit in the terminals, and can be prised out from
the rear using a suitable tool such as a knife blade.
RS 232| Interface for firmware-updates and for computer-controlled operation of device
functions through home-automations-systems (CRESTRON, AMX, etc.).
Detailled information regarding the RS232 interface and command tables can be found in the technical download section of the T+A  website http://www.taelektroakustik.de.
E LINK| Control output for T+A devices with E LINK inputs.
RC-IN   (E 2000)| If no Music Player / CD Player (E-Series) is present in your system: Input socket for E2000 remotre control sensor from the remote control set FBS100.
Mains switch| The primary mains switch is used to isolate the machine completely from the mains supply.
To operate the amplifier the primary mains switch must be moved to the ‘1’ position.
Mains input| This socket is for mains connection.
For correct connection refer to the sections ‘INSTALLATION AND WIRING’ and ‘SAFETY NOTES’.

Installation and wiring

Carefully unpack the unit and store the original packing material carefully. The carton and packing are specially designed for this unit and will be needed again if you wish to move the equipment at any time. Please read the safety notes in these instructions.
If the unit gets very cold (e. g. when being transported), condensation may form inside it. Please do not switch it on until it has had plenty of time to warm up to
room temperature, so that any condensation evaporates completely. Before placing the unit on a sensitive surface please check the compatibility of
the laquer and the unit’s feet on a non visible point. The quality and characteristics of the base on which your high-quality Hi-Fi equipment stands define the limits of sound quality which can be achieved. The base surface should be as heavy, rigid, hard and level as possible. The unit should be placed on a rigid, level base. When placing the unit on
resonance absorbers or anti-resonant components make sure that the stability of the unit is not reduced.
The unit should be set up in a well ventilated dry site, out of direct sunlight and away from radiators.
The unit must not be located close to heat-producing objects or devices, or anything which is heat-sensitive or highly flammable. When installing the unit on a shelf or in a cupboard it is essential to provide an adequate flow of cooling air, to ensure that the heat produced by the unit is dissipated effectively. Any heat build-up will shorten the life of the unit and could be a source of danger. Be sure to leave at least 10 cm free space above the unit for ventilation. If the system components are to be stacked then the
amplifier must be the top unit. Do not place any object on the top cover. Mains and loudspeaker cables, and also remote control leads must be kept as far away as possible from signal leads and antenna cables. Never run them over or under the unit. A complete connection diagram is shown in ‘Appendix A’ .

** Notes on connections:**

• Be sure to push all plugs firmly into their sockets. Loose connections can cause hum and other unwanted noises.
• When you connect the input sockets of the amplifier to the output sockets on the source devices always connect like to like, i. e. ‘R’ to ‘R’ and ‘L’ to ‘L’. If you fail to heed this then the stereo channels will be reversed.
• When connecting a recorder be sure to connect the IN sockets of the recorder to the OUT sockets of the integrated amplifier, and the OUT sockets of the recorder to the IN sockets of the integrated amplifier.
• If the remote control module is installed connect the plug on the E 2000 remote control receiver (optionaly obtainable remote control set FBS100) to the socket marked RC-IN E 2000. The E LINK socket of the integrated amplifier should be connected to the E LINK socket of the source devices (see ‘Wiring diagrams’).
• To achieve maximum possible interference rejection the mains plug should be connected to the mains socket in such a way that phase is connected to the mains socket contact marked with a dot (“). The phase of the mains socket can be determined using a special meter. If you are not sure about this, please ask your specialist dealer.

We recommend the use of the T+A  ‘POWER LINE’ ready-to-use mains cable and the ‘POWER BAR’ mains distribution panel which is fitted with a phase indicator as standard.
When you have completed the wiring of the system please set the volume control to a very low level before switching the system on.
Switch on the loudspeaker outlet to which your speakers are connected and switch the integrated amplifier to the listening source which you wish to hear. You should now hear the music.
If you encounter problems when setting up and using the integrated amplifier for the first time please remember that the cause is often simple, and equally
simple to eliminate. Please refer to the section of these instructions entitled ‘Trouble shooting’.

Loudspeaker and signalcables
Loudspeaker cables and signal cables (inter-connects) have a significant influence on the overall reproduction quality of your sound system, and their importance should not be under-estimated. For this reason**T+A** recommends the use of high-quality cables and connectors.
Our accessory range includes a series of excellent cables and connectors whose properties are carefully matched to our speakers and electronic units, and which harmonise outstandingly well with them.
For difficult and cramped situations the **T+A** range also includes special-length cables and special-purpose connectors (e. g. right-angled versions) which can be used to solve almost any problem concerning connections and system location.
Mains cables and mains filters
The mains power supply provides the energy which your sound system equipment needs, but it also tends to carry interference from remote devices such as radio and computer systems. Our accessory range includes the specially shielded ‘POWER FOUR’ mains cable, ready-to-use ‘POWER LINE’ mains cable with integrated shell-type filters and the ‘POWER BAR’ mains filter distribution board which prevent electromagnetic interference from entering your Hi-Fi system. The reproduction quality of our systems can often be further improved by using these items. If you have any questions regarding cabling please refer to your specialist **T+A** dealer who will gladly give you comprehensive expert advice without obligation. We would also be happy to send you our comprehensive information pack on this subject.

If you find it impossible to solve a problem with the help of these notes please disconnect the unit from the mains and ask your authorised **T+A** specialist dealer for advice.

Machine does not switch on (green LED does not light up).| Cause 1: Mains lead not plugged in correctly.
Remedy: Check connection, push connector in firmly.
---|---
Cause 2: Mains fuse burned out.
Remedy: Have the mains fuse replaced by an authorised specialist workshop. The rating of the replacement fuse must agree with the specification printed on the unit.
| Cause 3: Mains switch on the back panel not switched on.
Remedy: Switch the mains switch on.
|
The unit does not respond to commands.| Cause: Static discharge or powerful interference (e. g. lightning) have corrupted the processor memory.
Remedy: Disconnect mains plug. wait about 1 minute and re-connect. Switch unit on again.
|
Machine responds correctly to manual operation of the buttons, but does not respond to remote control commands.| Cause 1: E LINK cable between Power Plant and Music Player is not property connected.
Remedy: Please check and properly install the E UNK cable
Cause 2: Incorrectly inserted batteries or flat batteries in the remote control handset. Remedy: Re-install batteries correctly or fit new ones.
Cause 3: No Music Player / CD Player present.
Remedy: Please install the remote control set FBS100 available from your WI dealer.
|
The source devices

Remedy: Press The corresponding source button on the remote control handset and try again.
Cause 2: The source device is not connected via an E UNK cable.
Remedy: Complete the connection as shown in the wiring diagram.
|
Loud humming noise from the loudspeakers.| Cause: Poor contact between the Cinch plugs and sockets, or a faulty Cinch cable. Remedy: Please check all connections and cables thoroughly.

No output signal at the
loudspeakers; the LED
above the MUTE button
flashes (the PROTECTION
circuit has tripped).

| Cause 1: The PROTECTION circuit has tripped due to overheating or overloading.
Remedy: Reduce volume and wait for about 20 seconds. If the unit does not switch on again automatically, it has become too hot and should be left switched off for a few minutes to cool down.
Cause 2: Short-circuit in the speaker leads, e. g. stray wire ends touching at the speaker terminals, or mechanical damage to the cables.
Remedy: Check speaker leads and terminals, twist wire ends together neatly, replace damaged cables.
Cause 3: Overloading due to poor earth contact.
Remedy: Disconnect input cable and wait to see if the amplifier switches back on again; if so, check the input lead and replace if necessary.
Unit switches off repeatedly at fairly high volume levels| Cause 1: Overheating due to heat build-up.
Remedy: Set up the unit in such a way that an unobstructed flow of cooling air is
guaranteed.
Cause 2: Overheating through insufficient loudspeaker impedance.
Remedy: Use only loudspeakers of at least 4 Ω impedance (DIN rating). That means a minimum impedance of > 3.2 Ω.
Flat sound image, insufficient bass response.| Cause: The loudspeaker cables are connected with reversed polarity.
Remedy: Check the speaker connections at the loudspeakers and at the integrated amplifier’s speaker terminals; correct if necessary.

Glossary

AUX| Universal pre-amplifier input (AUX = auxiliary input) for connecting high-level
signal sources (i.e. signal sources with an output level between 0.25 V and 3,5 V).
---|---
Balance| The balance control provides infinite adjustment of level between right and left
channels (shift of stereo centre), e. g. to compensate for asymmetric speaker positioning.
To avoid any adverse effect on the sound, the balance range is limited to +6 dB / -8 dB. It is never desirable to reduce the volume of one stereo channel to zero.
dB| The unit of measurement for electrical levels is the deci Bel (dB).
E LINK| Control interface for remote control of T+A systems. The CD player / Music
Player receives the infra-red remote control signals and passes then on to the
power amplifier and to the source devices.
FLAT| In FLAT mode the signals pass along the shortest possible signal paths within the unit. All sub-assemblies which are not absolutely essential (e. g. the tone controls) are by-passed by means of high-quality gold-contact relays in this mode. The frequency response and phase response of the unit are absolutely linear in this mode of operation. This means that the FLAT setting provides the most faithful reproduction and the highest possible quality, and it should always be selected if the tone controls are in the centre position in any case.
Loudness| A volume-dependent tone control (Loudness) circuit which compensates for
the frequency-dependent sensitivity of the human ear at very low volume levels.
At very high volumes the loudness circuit has absolutely no effect, but as
volume is reduced the bass and upper treble are lifted, in order to compensate
for the reduction in sensitivity of the human auditory system at low levels.
MC| Some analogue turntables are fitted with dynamic sound pick-up systems (MC

Moving Coil). The amplifier can be fitted with an optional high-quality MC phono
pre-amplifier module whose input impedance and input sensitivity can be
adjusted to match all currently available dynamic pick-up systems.
MIM| Some analogue turntables are fitted with magnetic sound pick-up systems (MM
= Moving Magnet). The amplifier can be fitted with an optional high-quality MM
phono pre-amplifier module whose input impedance and input sensitivity can be
adjusted to match all currently available magnetic pick-up systems.
Source device| The term source device refers to those elements of a Hi-Fi system which
provide a sound signal, such as tuners, CD players, recorders etc. (signal
sources). We have to differentiate between listening sources and recording sources.
– A listening source is the device to which you are currently listening. This device can be remote-controlled.
– A recording source is a source from which a recording can be made using a recorder (TAPE). A recording source cannot be remote-controlled.
Update / Upgrade| This T+A unit can be kept up to date with the current state of development by
fitting an update or upgrade.
– An Update expands the unit’s operating facilities by the installation of a new
program memory.
– An Upgrade involves the installation of replacement sub-assemblies or auxiliary modules. The installation or conversion work is carried out by your specialistT+A dealer.
Volume control| The amplifier features a two-stage volume control which enables the unit to
work at a high level of amplification in the input stage of the pre-amplifier,
without risking overloading the pre-amplifier.
This is the responsibility of the first volume control. In the subsequent stages of
signal processing the amplifier has a higher-level signal to handle, and this in turn significantly reduces hiss and crossover distortion where the signal passes through zero.
The second volume control reduces any hiss generated in the pre-amplifier at
low levels directly before the output stage.
